Product Details

FN5-12R(L) Model indoor AC HV load isolation switch and fuse combination apparatus is developed and designed based on

international technology and national power supply requirement, it passes all type tests and trial-operation inspections. The apparatus conforms to IEC420: AC load breaker switch and fuse combination apparatus. (1990 edition) and GB3804: 3-63kV AC HV load break switch. Compare to international product, it keeps up with technical level with small volume and weight. It is applicable in ring main unit and prefabricated substations as well as 12kV wiring and power distribution system.

The load isolation switch realizes three working positions: power making, power breaking and earth. It applies to power system of rated voltage 6-12kV, 50/60Hz breaking load current, overload current and short-circuit current.
